2 Claims, 2 Drawing Figures COIN DEGREE FINDER This invention relatesgenerally to accessories used by coin enthusiasts and coin collectors.

A principle object of the present invention is to provide a coin degreefinder for use with various different denomination of coins to find towhat degree the opposite side of a coin are off clockwise orcounterclockwise respective to each other.

Another object is to provide a coin degree finder which together withset instructions would be issued as to the center of each coin.

Another object is to provide a coin degree finder which may be producedin two types; one of which includes a set of different size insertsadapted for different coins, and the other set not including theinserts.

Other objects are to provide a coin degree finder which is simple indesign, inexpensive to manufacture, rugged in construction, easy to use,and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawings wherein:

FIG. 1 is a side cross sectional view of the invention shown assembled.

FIG. 2 is a view of the different parts of the invention shownseparated.

Referring now to the drawing in detail, the reference numeral representsa coin degree finder according to the present invention wherein there isa circular protractor 11, made of transparent plastic material, theprotractor having scribed on one side thereof a pair of cross lines 12and 13 at right angle to each other, and degree calibrations 14 whichread from0 to l80 on each opposite side of edge 15. The cross lines 12and 13 are associated with the calibrators 14 so that line 12 extendsfrom 0 to 180 while the line 13 extends from 90 calibration on one side,to the 90 calibration on the other side. The calibrations on the leftside of the 0 are indicated at 16 to be counter clockwise, while thecalibrations on the right side of 0 are indicated at 17 to be clockwise.

A central depression 18 on the protractor 11 is concentric with thecircular edge the depression 18 being of a size of a silver US. dollarcoin l9, and which accordingly can be placed therein. The depth of thedepression is at least the thickness of the thickest coin for which itis intended to be used.

A circular lid 20 made of transparent plastic, is adaptable to snap overthe protractor; the lid including a circular top panel 21 with a singlecross line 22 inscribed across its center, and the panel edge having aflange 23 for snapping around the protractor edge 15.

When the coin degree finder is intended to'be used for different sizesof coins such as a one-half dollar 24, quarter 25, dime 26, nickel 27 orpenny 28, then the present invention also includes inserts 29 through 33for associating with the respective coin; each insert consisting of afiat circular disc 34 which is of transparent plastic; all inserts beingof a same size to fit into the depression 18. A single cross line 35, isscribed centrally across each disc 34, and a central opening 36 throughthe disc is ofa size so to fit the particular coin, as shown in thedrawing.

In operative use, it is now evident how the coins may be utilized withthe invention. By aligning a front side of the coin with the cross linesof the lid 20 and the insert 29, and/or the cross lines of theprotractor, he can then look at the rear of the coin so to check to whatdegree the rear side of the coin design is out of line respective to thefront side design of the coin.

As indicated, the device may be manufactured including the inserts sothat it is adaptable for measuring different denominators or coins, orit can be manufactured without the inserts in which case the protractordepression is of a size so to receive the particular coin denominatoronly. Thus different finders would be manufactured for the differentsizes of coins.

While changes may be made in the detail construction it is understoodthat such changes will be within the spirit and scope of the presentinvention.

lclaim:

1. In a coin degree finder, the combination of a protractor and a lid,said protractor and lid having means whereby a design stamped on oneside of a coin may be measured to a design stamped on an opposite sideof said coin, so to see to what specific degree clockwise or counterclockwise, said designs are angularly off respective to each other,wherein said protractor is a circular disc of transparent material withdegree calibrations therearound and cross lines scribed thereupon, saidprotractor having a central depression for placement of a coin therein,and said lid comprises a circular panel of transparent material with across line scribed thereupon, said lid having a flange to snap aroundsaid protractor.

2. The combination as set forth in claim 1, wherein said finder alsoincludes a set of inserts selectively receivable in said depression,each insert being of transparent material with a cross line scribedthereupon, and each insert having a central circular openingtherethrough, said opening being of a size adaptable to receive aparticular size of coin.
